By reading TM0n, the count value can be read.
If M is set to CR00n, the interval time is as follows.
• Square wave frequency = 1 / [2 × (M + 1) × Count clock cycle]
Setting CR00n to 0000H is prohibited.
Usually, CR01n is not used for the square-wave output function. However, a compare match interrupt
(INTTM01n) is generated when the set value of CR01n matches the value of TM0n.
Therefore, mask the interrupt request by using the interrupt mask flag (TMMK01n).
